(2.) Flowers panicled : stems climbing. 
12. C. pauciFLorA, Nutt.—Climbing, but inclined to gr ow erect or 
bushy, smooth or somewhat silky pubescent, short jointed ; leaves 
pinnate and ternate, short and fascicled; leafiets 3-5, only 3’’-9” long, 
cuneate obovate to cordate, obtuse, mostly 3 toothed or lobed, petioles 
slightly pubescent; flowers axillary, solitary or few and panicled, on 
slender pedicels; sepals thin, 4’’-6” long ; akenes glabrous, with slender 
plumose tails. * 
13. C. Drummonpu, Torr. & Gr.—Stem slender, angular, somewhat 
hairy ; leaves pinnate, silky villous beneath, sparingly hirsute on the 
upper surface; leaflets mostly 5, rhombic ovate, incisely 3 lobed, the 
lobes acute; panicles about as long as the leaves, trichotomously 
divided; sepals 4, white, oblong, villous externally; tails of carpels 
more than 2 inches long, densely plumose.t 
14, C. Vireintana, Linn. (C. Catesbyana, Pursh.{ )—Stem climbing 
8-15 feet high, supporting itself by the long petioles, smooth ; leaves 
ternate, with three ovate, acute leaflets, which are cut or lobed, and 
somewhat heart shaped at the base; flowers panicled, polygamo-dioeci- 
ous, with 4 white, obovate, thin, spreading sepals; carpels with long 
plumose tails.§ 
Var. BRACTEATA, DC. (C. holosericea, Pursh.||)—Pubescent. “ Leaf- 
lets ovate-lanceolate, entire.” 
In uniting C. holosericea and C. Catesbyana with C. Virginiana, 
I have been influenced by several considerations. The first species is 
a very obscure one, described by Pursh from dried specimens in the 
herbarium of Walter, and differs from C. Viryiniana, in being pubes- 
cent, and in having entire instead of serrate leaflets, two characters 
which are much too variable to establish specific rank. A specimen

1 C. Catesbyana, Pursh.—Stem climbing, minutely pubescent; leaves bi-ternate, or pin- 
nately 5-foliate; leaflets ovate, often slightly cordate, small, mostly 3-lobed, the lobes en- 
tire, acute or acuminate; flowers mostly dioecious, in axillary divaricately forked cymes ; 
sepals linear oblong; carpels short tailed, plumose. (Pursh, Fl. Am., vol. ii., p. 736, Torr.

| OC. holosericea, Pursh.—Stem climbing, downy or silky in all its parts; leaves ternate, 
pubescent both sides; leaflets entire, oblong lanceolate; flowers dicecious, small, white, in 
paniculate corymbs, few-flowered; linear petals longer than the stamens; carpels long 
plumed. (Pursh, J. c.. vol. ii., p. 384. Wood’s Cl. Bk., p. 201.)
